EDWARD M. HEYLMAN, OF SOUTH BEND, INDIANA, ASSIGNOR T0 OLIVER GHILLED PLOW WORKS, OF SOUTH BEND, INDIANA.

COLTER AND J'OINTER ATTACHMENT FOR FLOWS.

Application filed February 2, 1915.

To all whom it may concern:

Be it known that I, EDWARD M. HEYL- MAN, a citizen of the United States, and a resident of South Bend, in the county of St. Joseph and State of Indiana, have invented certain new and useful Improvements in Colter and Jointer Attachments for Plows; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to improvements in colter and j ointer attachments for plows and particularly to a structure which combines a colter and jointer for simultaneous operation,one object of the invention being to so mount a rolling colter that the same will be maintained in true working position and to mount the jointer in such relation to the colter that it will properly perform its functions, at the same time obviating the liability of the wedging of trash between the jointer body and the rolling colter.

With this and other objects in view, the invention consists in certain novel features of construction and combinations of parts as hereinafter set forth and pointed out in the claims.

In the accompanying drawings; Figure 1 is a view showing the application of my improvements to a plow; Fig. 2 is an enlarged side elevation of the attachment; Fig. 3 is an elevation similar to Fig. 2, viewing the attachment from the opposite side; Fig. A is a sectional view showing the colter mounting, Figs. 5, 6 and 7 are detail views of the arm with which the colter and jointer are connected, Fig. 8 is a section on the line 8.8 of Fig. 4, and Fig. 9 is a section on line 99 of Fig. 3.

1 represents a vertically disposed standard having a crank 2 at its lower end, and with this crank, one end of an arm 3 for carrying a rolling colter 4 and a jointer 5, is connected, as hereinafter particularly described. The standard 1 may be secured to the frame 6 of the plow or it may be attached directly to the plow beam. In the drawing, my improvements are shown as applied to a sulky plow, the frame of which is provided with an upwardly projecting arm 7 which forms a lateral seat for the standard 1, and the latter may be clamped to the seat by means of an eye bolt 8. By loosen- Specification of Letters Patent.

Serial No. 5,672.

ing the clamping bolt 8, the standard may be adjusted vertically or it may be turned (its upper end being made angular as at 9 for the accommodation of a wrench or lever), for the purpose of adjusting the colter and jointer, relatively to the plow base 10.

In order that the arm 3 shall more effectually withstand the lateral and torsional strains to which it may be subjected, said arm is made hollow. The forward portion of the arm 3 is curved laterally and made with a split head 11 to receive the cranked lower portion 2 of the standard, said' head being provided with perforated lugs 12 for the accommodation of a bolt 13 whereby the arm 3 is connected with the standard. A collar 14: is secured to the lower end of the crank 2 to sustain the arm 2 and'the soil engaging parts carried thereby, when said parts are raised, and this collar is provided with a stop lug 15 to cooperate with stop lugs 16 on the arm 3 to limit the pivotal movements of the latter.

The hollow arm 3 is made somewhat onlarged or elongated vertically as at 17 and from this rear end portion of the arm, a flange or web 18 depends. Formed integral with this depending flange or web, is a bearing box 19 which is disposed substantially at right angles to the arm 3. The bearing box 19 is provided interiorly with shoulders 20 against which the inner ends of wooden bushings 21 abut,said bushings being pre vented from rotation by means of V-shaped keys 22 within the bearing box. A tubular spindle 23 mounted in the bearing box, is revoluble within the wooden bushings, and is provided at one end with a head 2% having a shoulder 25 to bear against one end of the bearing box and a shoulder 26 to engage one end of the adjacent wooden bushing 21. The outer face 27 of the head 2-1 is machine finished and the colter blade l rests against this face, a central boss 28 on said head entering a central hole in the colter and this boss is provided with a key 29 to enter a notch 30 in the colter to prevent the same from turning. A groove 31 is formed around the boss 28 so that the face 27 can be machine finished without interfering with the key 29. A cap 32 engages the opposite face of the colter disk and is perforated for the passage of a bolt 33. This bolt also passes through the tubular spindle 23 and is threaded at one end to receive a nut 3 1 which bears against the cap 32. The other end of the bolt 33 is made with a head 35. A washer'36 engages the end of the'spindle I and the end of the bearingbox and between this washer and the head 35 of bolt 33, a

disk or washer 37 (which may be madeof card board) is placed to make a tight joint and .prevent grease from being forced between the'hole in the spindle and the bolt.

The spindle is made with a finished surface to insure its true running andby providing alfinished face 27 against which the colter disk bears, the true running of the colter is insi'ired. The end of the bearing box 19 nearest the head of the spindle, is cut-away as atf37 to permit the discharge of dirt which might find its way betweenthe bear- V of a grease cap 38.

ing box andlthe'spindle.

The ,outerend of the bearing box '19 is threaded exterior-1y for the accommodation This cap is provided exteriorly with beveled lugs 39, either of .whi'ch may be engaged by a'spring 40 to prevent said cap from turnlng. The spring 40 is secured to the depending. flange 18 of arm 3 and said flange and the bearing box 19 are provided at each side of the spring with ribs 41 to retain said spring in position parallel with the bearing box over which it projects." It will be observed that by curving the forward end'of'the arm 3 7 is provided with a threaded hole for. the

passage of a bolt 43 which passes transversely through said hollow arm and serves to pivotally connect the arm 42 therewith. The rear portion of the arm 42 is bent laterally so as .to project beyond the vertical plane, of the opposite side of the colter, as

, shown at 44,and from the free end of this laterally projecting portion of arm 42, a

shank or standard 45 depends for the reception of a jointer body 5. The mold board and shareportions 47, 48 of the ointer are secured to a frog 49,theshank of whichis seated against the standard .45 and is adjustably clamped thereto bymeans of jaws 50 which engage in slots in the shank of the frog and are clamped to the standard by means of a bolt 51.

' arm 3 are made with elongated holes or slots 52 and one or both outer faces of the arm 3 adjacent to said slots may be serrated,

.as' shown at 53.- 'A bolt 54 passes trans- 1versely through the slots 52 and threaded through a vholein the arm 42 and between the nuts or heads 55 on said bolt and the serrated portions of thearm 3, serrated disks disk.

' The walls of he enlarged portion of the .or washers 56 are interposed. By these means, the arm 42 may be adjusted relatively to the arm 3 and thus efiect adjustment of the jointer relatively to the colter The coltermay also be adjusted vertically and laterally on the standard 45 by loosening the bolt, and said colter will be securely held in the position to which it may be adjusted by the adjustable connections between the jointer and standard and the adjustable connections between the arms 42 and 3.

The constructions and arrangements of parts above described will permit the jointer to be accurately disposed in the most advantageous relation to the colter to efieet the best service of both the jointer and. colter. The jointer is so set that the point of the jointer share will be closer to the colter disk than the rear portion of the edge of the share or the edge of the mold board of the jointer. The point of the jointer share may be about of an inch from the face of the colter disk, and the edge of the rear portion of the share may be about :1; of an inch from said face of the colter disk. These proportions may be varied somewhat, but it is importantthat the point of the share shall be nearer to the disk than is the butt of the share and the mold board. By

such construction, trash, such as weeds,

grain stubble, etc., cannot wedge between the jointer body and the colter disk, and hence the free rotation of the colter disk will not be interfered with. It is also desirable that the point of the ointer shall be approximately under the axis of rotation of the colter disk so that the colter will cut the trash in advance of the jointer body and accumulation of trash on the j ointer shank or standard will be obviated.

Various changes might be made in the details of construction of my invention without departing from the spirit thereof or limiting its scope and hence I do not wish to restrict myself to the precise details herein set forth.

Having fully described my invention what I claim as new and desire to secure by Letters-Patent, is:

1. The combination with supporting means and a rolling colter, of a jointer, means supporting the jointer in rear of the axis of the colter with the point of the jointer share disposed under and approximately in vertical alinement with the axis of the colter and closer to the face of the colter than is the butt of said share, said jointer having its rear portion. projecting above the plane of the colter axis.

2. The combination with a standard, an arm attached thereto, and a colter carried by said arm, of an arm having vertically adjustable connection with said first-mom tioned arm, and a jointer adjust-ably supported by said adjustable arm and disposed below and in rear of the axis of the colter, said jointer being so disposed that the point of its share will be closer to the face of the colter than is the butt of said share.

3. The combination with a support, and a rolling colter having a mounting on said support, of an arm pivoted to said support and terminating in an upright member at the opposite side of the colter from said support, means for holding said arm at different vertical adjustments, and a jointer carried by the upright member of said arm, said jointer having the point of its share nearer to the face of the colter than is the butt portion of said share.

4. The combination with a support, and a rolling colter having a mounting on said support, of an arm pivotally attached to said support and terminating in an upright member at the opposite side of the colter from said support, means for holding said arm at different adjustments, a jointer adjacent to the face of said colter, and means adjustably connecting said jointer with the upright member of said pivoted adjustable arm.

The combination with a support and a rolling colter having a mounting thereon, of a jointer disposed in rear of the aXis of said colter and having the point of its share approximately under the axis of the colter and normally out of contact therewith, the point of the share being nearer to the face of said colter than is the butt portion of said share.

ing elongated slots, a bolt passing through said slots and the other arm, means for securing said bolt and arm at different adjustments, a standard carried by said last mentioned arm, and a jointer attached to said standard.

8. The combination with a standard, of an approximately horizontal arm having a bifurcated end embracing said standard, a bolt passing through the projecting portions of the bifurcated end of the arm, a colter disk mounted on said arm, a collar secured to the standard below said arm, a stop on said collar, and stops on the arm to cooperate with the stop on the collar.

In testimony whereof, I have signed this specification in the presence of two subscribing witnesses.
